School goes on.....I have a home built all-leadscrew 3-axis 24" x 48" cnc router w/ Xylotex steppers and I just bought an optical breakout board through which I want to run limit switches. I have wired all the switches together using the NC (normally closed) pin, put 5 VDC through the switches, and hooked it to opening #15 on the board. I then went to the ports and pins input section and activated the x, y, and z plus and minuses, and entered pin #15 for all of them. When I turn everything on and trip a limit switch, nothing happens and none of the LEDs light up on the diagnostics page. Anyone know what I'm doing wrong?
Also, when I use VCarvePro to calculate a toolpath, it asks me what version of Mach 3 I want to use for the postprocessor, and it has 4 choices (Mach 3 Arcs, Mach 3 Line, etc.) How do I know which version I have?
Thanx again, Bob
